Michael Stephen Oliva remains in a hospital under federal guard after the incident Friday at First Security Bank in Trimble.

According to court documents, Oliva came into the bank, put on a black mask and pointed a realistic-looking plastic gun at a teller and ordered her to give him money. The employee dropped to the floor and asked a colleague for help.

Investigators said a second employee, who was in an office, saw Oliva pointing a gun at the teller. The employee retrieved a revolver and fired two shots, one of which hit Oliva in the jaw.

Police said Oliva ran out of the bank without any money and sped off in a silver Dodge Stratus at speeds approaching 100 mph. Police followed the car until they were able to flatten the tire with spike strips.

Oliva was arrested and taken to an emergency room.

Prosecutors said his medical condition has prevented him from making a court appearance.
